"Apple, the world's most profitable technology company, doesn't design iPhones here. It doesn't run AppleCare customer service from this city. And it doesn't manufacture MacBooks or iPads anywhere nearby. Yet, with a handful of employees in a small office here in Reno, Apple has done something central to its corporate strategy: it has avoided millions of dollars in taxes in California and 20 other states." Sure, this is all legal for companies to do (and Apple obviously isn't alone) but it does show you how much sense of morality companies have. Answer: none. But hey, it's legal, and the law is never wrong, right?

It is immoral to profit from all the benefits a society offers while refusing to contribute back your part to keep that society running.

The only reason you have something to keep in the first place is that you had an education, infrastructure, justice and protection - all provided by the society you live in. It may not be perfect, but I guess you can always move to a free country such as Somalia.
